HOSE oourmne f Application led May 25,

This invention relates to an improved hose coupling, and has for one ofits principal objects the provision of means for connecting links ofhose or the like whereby a secure non-leakable connection is provided,and further whereby undesirable buckling of the hose is prevented. Y

One of the important objects of this invention is the provision in ahose coupling of means for so connecting two or more links of hose orthe like, whether air, water, or any other kind of hose, whereby freerelative rotation between the sections is permitted while at the sametime any possibility of leakage at the connection is eliminated.

Another important object of this invention is to provide in a hosecoupling, means for so connecting lengths of hose or tubing,particularly hose designed to carry air under pressure, that undesirablekinking, buckling, and consequent kicking ot the hose is avoided,thereby lessening the danger of injury to the operators or users.

Other and further important objects of the invention will be apparentfrom the dis` closures in the accompanying drawings and followingspeciiication.

The invention, in a preferred form, is shown in the drawing andhereinafter more fully described.

In the drawing:

Figure 1 is a plan view of the improved hose coupling of this invention,showing the same connecting two sections of hose, tubing, or flexiblepipe.

Figure 2 is a detail sectional view of the coupling.

Figure 8 is a perspective View of the nipple. Y

As shown in the drawing:

The reference numeral 10 indicates generally the main portion 'or casingof the hose coupling', this being shaped as shown, and peripherallyformed adjacent its open end in the shape of a hexagonal nut or the likeas illustrated at 12. The interior of this end is screw-threaded as at111 for the reception of a correspondingly screw-threaded male member16, this member being'formed integral with the other portion of thecoupling 18.

1931. SerialrNo. 539,647.

This last p .ortionis also'formed with a hexagonal nut-shaped face asillustrated at 20, thereby` ajiordin'gV a- ,V convenient Vmeans oftight-lyfconnectingthememberstogether. f iyThe` interior of the casing`10 lis.- cylindri-f callyshaped and is 'bored vsmoothto vslidably and.rotatably receive. the upper end 22 of a nipple24.- Thellpper end ,22isfground so asf'to closely correspond to the interior fcylindrical'portion of the casing 10,whi1e.at, 60

the same time allow of a free rotation and vsliding therein. An annularpackinglring 26 surrounds the 'nipple `portiony 24 `beneath theshoulderfelement 22 and the lower face of V y this packing ring isadapted to contact with 6I ,anannular shoulder 28 formed -in the lowerlendof the casing 10. `'lfheinternal diameter of the opening at thelower end of the casing 10 is such as to closely4 correspond to acarefully.V ground section 30 of the nipple 2410 wherebyarotatable;andfslidablefit is here alsoy provided; which, however, atthe same time-allows of a free movement between the parts.

` and the packing 26 will come into close con- 85 tact with the shoulder28. The more pre ssure existing in the interior ofthe hose line, themore close will be the contact between the packing and this shoulder,and the less possibility of leakage. Additionally, free ro-` ,90 tationbetween the sections of hose at the coupling will be permitted, therebyV.avoiding kinks. Such kinking forms the most undesirable and actuallydangerous portion of the work when operating with air lines undery highpressure, such as those employed for riveting machines and the like, asthev sudden straightening out of aikink in such air line sometimesresults in throwing the operator a considerable'distance, and if theoper-,y- IDO The extending ends of the elements 18 and `715 ator is inan insecure position, it might result in his dislodgment, fall, and aconsequent serious accident. By the use of this invention, kinks areautomatically eliminated, as 5 free rotation between the sections at alltimes is fullypermitted. Y Y f Many-changes may be made and numerous 'Ydetails of construction 4varied throughout a `vvide range Withoutdeparting from the 10"principles` of this invention, and therefore, thepatent grantedhereon shouldnot be limit-V ed otherwise than asnecessitated by the prior art.

What is claimed is:

15 In a hose coupling, a tubular member, an internal flat annularshoulder at one end of said tubular member, a corresponding hosereceiving element slidably and rotatably y mounted fory unobstructedmovement inthe '520- shouldered end' lof said tubular'member saidyshouldered end comprising a chamber for the reception and operation ofthe hose receiving element, a corresponding shoulder on the hosereceiving element, a second hose re v525 ceiving elementscrew-threadedly mounted 'in the other end of said tubular member, andga packingon the'iirst hose receiving elementV adjacent the shoulder,said packing adapted l to be forced i-nto air and liquidtight contact "530 with the iat shoulder oit Vthe tubular member upon theapplication ofpressure thereto.

` In testimony whereof the nventors signature is aiixed.
